David Charleston, once a world‑renowned journalist, now lives in isolation as the keeper of Thunder Rock lighthouse on Lake Michigan, refusing his pay and seeing only the monthly inspector. He imagines conversations with the spirits of a 19th‑century packet ship that sank with sixty passengers, hearing their hopes, fears and stories—a spinster yearning for independence, a doctor exiled for unconventional methods, and his own desperate 1930s pleas about fascism that fell on deaf ears. These imagined dialogues gradually restore his sense of purpose and hope for the future.

During the late 1930s, David Charleston is a driven campaigning newspaper journalist who openly challenges fascism and Britain’s policy of appeasement. He seeks to alert readers to German rearmament and the dangers of ignoring events in Europe, but the editor silences his reports. Frustrated, he resigns and embarks on a country-wide speaking tour under the banner of the slogan:
Britain, Awake!
Yet the public response is muted; crowds chat through newsreels and drift away for snacks, signaling a complacent mood as ominous developments unfold. Charleston senses that his homeland would rather sleep through looming peril than confront it, a realization that hardens into a resolve to seek a safer distance from a world on the brink.
Seeking drastic change, he crosses the Atlantic and accepts a solitary post as a lighthouse-keeper on Lake Michigan. The rock beneath the light bears a commemorative tablet listing the names of European immigrants who perished ninety years earlier when their ship sank in a violent storm. As weeks stretch into months, Charleston’s isolation gives rise to a haunting presence: the specters of the lost souls begin to speak, sharing stories of sorrow, escape, and unfulfilled dreams that echo Charleston’s own sense of failure and longing. The ship’s captain, Capt. Joshua Stuart, emerges as the only ghost aware that he is dead and that the world around him is not stuck in 1850. He acts as a mediator, guiding Charleston through the spectral testimonies while maintaining a fragile boundary between the living and the dead.
Charleston learns of Ellen Kirby, described as a proto-feminist persecuted for her progressive views, whose trials resonate with his own sense of moral urgency. He becomes emotionally entangled with the Kurtz family: Stefan, a forward-thinking medical man, and his daughter Melanie Kurtz, who seems to share a ghostly attraction toward Charleston, a pull he finds himself returning.
As the weeks pass, Streeter, an old colleague, arrives with concern about Charleston’s welfare after discovering that his pay cheques have not been cashed for months. Streeter is puzzled and alarmed by Charleston’s detachment, and he presses him to rejoin the living world. Meanwhile, the spirits’ presence becomes more insistent; they begin to question where they are and what time it is, blurring the lines between memory and reality. Charleston reluctantly allows Melanie to read the tablet, and he explains that the civilization they once knew is nearing its end. He reveals that, as figments of his imagination, they no longer need to appear—yet they do not vanish.
The reply from the spectral community is sobering. [Stefan] urges him that retreat is a form of cowardice and that the fight for what is good and right must be faced, regardless of the consequences. The revelation forces Charleston to confront a choice: stay in self-imposed exile or return to Europe to continue the struggle for truth and justice against the encroaching evil that threatens the continent. The resolution is both personal and political, a moral turning point that reframes Charleston’s purpose.
In the end, Charleston chooses to abandon solitary withdrawal and to recommit himself to the fight for a better future. He resolves to return to Europe, carrying with him the memories of those who suffered and the conviction that resilience and advocacy can still shape the course of history. The story leaves us with a quiet, steadfast message: courage is not the absence of fear but the willingness to stand up for what is right, even when the world seems oblivious or unaccommodating to the truth.
